To all whom t may concern.'

Be it known that I, HARRY O. KAMMER- DnrNER, a citizen of the United States, residing at Echo, in the county of Armstrong and tate of Pennsylvania, have invented certain ynew and useful .Improvements in Rail-Joints; andl I do declare the following to be a full, clear, and eXact description lof the invention, such as will y.enable others skilled in the art to which it appert'ains to make and use the same.

This invention relates to an improved rail joint and one object of the invention is to provide improved means for interlocking the adjoining end portions of a pair 0f rails so that the rail sections will be held against longitudinal and transverse movement and further caused to move vertically together thus preventing the rails from moving out of the proper alinement and further making it unnecessary to provide fish plates or other similar means t0 hold the rails in close engagement with each other.

Another object of the invention is to so construct this joint that the two rail sections may be easily and quickly put together or taken apart.

Another object of the invention is to so interlock the tread portions of the adjoin` ing rail sections that a wheel may ride easily from one rail section to another.

This invention is illustrated in the accompanying drawings, wherein:

Figure 1 is a perspective view showing rail sections connected by the improved joint.

Fig. 2 is a view showing the improved rail joint in side elevation.

Fig. 8 is a transverse sectional view taken along the line 3-3 of Fig. 2.

Fig. l is a top plan view of the improved rail joint.

This improved rail joint is for connecting adjoining rail sections 1 and 2. The rail end 2 has its tread cut longitudinally from one end to provide a V-shaped pocket 3 which is of less width than thetread thus providing abutment shoulders 4 for engagement by the abutment shoulders 6 provided upon opposite sides of the tapered tongue 5 which extends from the tread portion of the rail end 1. The web portions of the two rail ends are cut to provide joints 7 and 8 which fit one upon the other, thus providing a good support for the rail ends. The base portion of the rail end 2 is cut to provide a tends outwardly into the base portion of the,

rail upon opposite sides ofv the web. This seat or pocket is provided with straight cut sides and in the; preferred form, the lseat is rectangular as shown i-n F igs. 1 and 4. The base portion of the rail end 1 is cut away to provide a tapered rib 11 which conforms to the contour of the neck 9 and tits into this neck. Side arms or wings 12 extend transversely of the rail end 1 and when taken together with the portion of the base between the arms will form a block for litting into the seat or pocket 10. It will thus be seen that when the rails are put together, the tongue 5 will fit into the pocket 3, the block formed by the side arms 12 will t into the pocket 10 and the rib 11 will be seated in the tapered seat 9. This construction will prevent the rails from moving longitudinally out of engagement with each other and will also prevent them from having transverse movement. It will be further noted that the weight of a train passing over the rail 1 will bring the end portions into tight engagement with the end 0f the rail 2 and the two rail sections will be held in close contact while the train is passing from one rail to another. ItV is only necessary to use spikes in connecting the rails with the ties and lish plates or other connecting means between the rail ends are not necessary. When desired, the spikes can be removed and the rails easily separated.

Iv claim:

1. A rail joint comprising adjoining-rail ends, one rail end having its tread out to provide an inwardly extending V-shaped pocket of less width than the tread and the second rail end having its tread provided with a tapered iinger fitting into said pocket, the web portions of the rail ends being cut to provide step joints, the base portion of one rail end being out to provide an inwardly and downwardly tapering neck leading to'an enlarged pocket at the base of the step joint and the second rail end having its base cut to provide a tapered rib litting into the tapered neck and straight cut side wings fitting into the pocket.

2. A rail joint comprising adjoining rail ends having their treads interlocked against independent transverse movement and their web portions being cut to provide step joints, the base portion of one rail end being cut to provide an inwardly and downwardly tapering neck leading t0 an enlarged pocket at the base of the step joint and the second rail end having its base out to provide a tapered rib fitting into the tapered neck, and straight out side wings itting into the pocket.

3. A rail joint comprising adjoining rail ends having interlocking treads and their web portions cut to provide step joints, the hase portion of one rail end being Veut to provideva tapered neck leading to an enlarged rectangular pocket having straight cut sides and the second rail end having its base out to provide side wings filling said pocket and a longitudinally extending tapered rib fitting into said neck.

4. A rail joint comprising adjoining rail ends having interlocking treads and their web portionsmeeting in edge Contact, the base portion of one rail end having a longitudinally extending "downwardly tapered passage leading to an enlarged pocket and the second rail end having its baseprovided with side wings tting into and filling said pocket, and a longitudinally extending downwardly tapered rib fittingv into Ysaid passage. f

In testimony whereof I khave hereunto set Iny hand in the presence of two subscribing witnesses. l
